Preg_match over multiple lines

My code is sometimes split over two lines like so:

enter image description here

I'm trying to match part of the URL by using the following regex:

https://www.url.com/(.*?)">Please Click Here

I have tried using /s and /m on the line but doesn't seem to match.

Any advice?

You don't need to use the s (single line) or m (multi-line) modifier here.

You could use something as simple as the following.

preg_match('~([^/]+)(?=">please\s+click\s+here)~i', $text, $match);
echo $match[1];

The i modifier is used for case-insensitive matching.

The problem is that "Please Click Here" won't match this:

Please Click
Here

The latter contains whitespace characters like \n, \r (maybe), and possibly \t. Although it doesn't look like it contains \t from the image you posted, it's better to try to handle that scenario, too. The \s expression will catch a simple space (), as well as each of these characters.

Use this regex instead:

https://www\.url\.com/(?:[^"]*)(?=">Please\s+Click\s+Here)

Edit: tweaked further to return only the URL, not "Please Click Here" and the ">.

For static url, basic search pattern would be:

/https:\/\/www\.url\.com\/([^\"]*)\"[^>]*>\s*Please\s+Click\s+Here/

But you better use $url as a variable and include it in regex pattern as follow:

/<a\b[^>]*\burl=\"$url\"[^>]*>\s*Please\s+Click\s+Here\s*<\/a>/i
